United enter chase for Hummels

Manager David Moyes is set to be handed £100m to improve a squad that has failed to impress in the opening two months of the season.

The reigning champions, who currently sit in ninth place having lost three of their opening seven games, only managed to bring in midfielder Marouane Fellaini during the summer despite being linked with a host of big names.

Germany international Hummels has a £29.5m release clause in his contract, and has also been linked with a move to Barcelona who themselves failed to land any of their defensive transfer targets in the close season.
